At last, a preview of the Jelly Bean-based CyanogenMod 10 has been released for the HTC One X! This indeed fixes our number one problem with the One X cited in the review: lag. On the One X with stock software with Sense 4.0, we found lack around every corner, which was surprising for such a high-end phone. Jelly Bean on the One X is super duper fast, whether browsing the web, opening folders, or moving between apps. In fact, we’d say that it’s a pinch faster than the already-fast CyanogenMod 10 port to the Galaxy S III we recently showed you. That said, installing CM 10 on your One X is relatively easy, but will require a couple of extra steps than the normal installation of a third party ROM (if you’ve ever done it). Note that the below instructions are only for the international variant of the One X. However, if you’re running the AT&T One X, there is an alpha CM10 build that you can install on your phone (though at this time, it’s rather buggy).
